Baking oven insulation (1), comprising at least a first insulating layer (2) composed of a fibre material, a metallic sheet material layer (3) and a second insulating layer (4) at least partially composed of a fibre material, wherein the first and second insulating layers (2, 4) are located at opposite sides of the metallic sheet material layer (3), wherein the first insulating layer (2) is an inner layer to be arranged immediately at the outer side of a cavity wall (12) of a baking oven (10) and immediately at the inner side of the metallic sheet material layer, and the second insulating layer (4) is an outer layer adapted to be spaced from the cavity wall (12) of the baking oven (1) wherein the first insulating layer (2) comprises a thickness d which enables the metallic sheet material layer to efficiently reflect the thermal radiation from the cavity wall and which enables the first insulating layer to reduce the heat conduction from the cavity wall to the metallic sheet layer (3). |
